A Sparkplug B data type code.

Values 1..=14 are the basic scalar types (valid as DataSet columns, template parameters, and property values). 15..=19 add UUID/DataSet/Bytes/ File/Template. 20..=21 are property-value-only (PropertySet/list). 22..=34 are the array types.

Implementations

impl DataType

pub const fn as_u32(self) -> u32

The integer code as it appears on the wire (datatype field, an unsigned 32-bit integer per tck-id-payloads-metric-datatype-value-type).

pub const fn from_u32(v: u32) -> Result<Self>

Parse a wire datatype code, rejecting unknown values (tck-id-payloads-metric-datatype-value).

Errors

Returns SparkplugError::UnknownDataType for codes outside 0..=34.

pub const fn is_basic(self) -> bool

true for the basic scalar types 1..=14, the only types permitted as DataSet columns and template parameters (tck-id-payloads-dataset-types-value).

pub const fn is_array(self) -> bool

true for the array types 22..=34.

pub const fn array_element_width(self) -> Option<usize>

For numeric/temporal array types, the fixed little-endian element width in bytes. BooleanArray/StringArray use special framing and return None, as do non-array types.

Trait Implementations

impl Clone for DataType

fn clone(&self) -> DataType

Returns a duplicate of the value.

fn clone_from(&mut self, source: &Self)

Performs copy-assignment from source.

impl Copy for DataType

impl Debug for DataType

fn fmt(&self, f: &mut Formatter<'_>) -> Result

Formats the value using the given formatter.

impl Eq for DataType

impl Hash for DataType

fn hash<__H: Hasher>(&self, state: &mut __H)

Feeds this value into the given Hasher.

fn hash_slice<H>(data: &[Self], state: &mut H)

where H: Hasher, Self: Sized,

Feeds a slice of this type into the given Hasher.

impl PartialEq for DataType

fn eq(&self, other: &DataType) -> bool

Tests for self and other values to be equal, and is used by ==.

fn ne(&self, other: &Rhs) -> bool

Tests for !=. The default implementation is almost always sufficient, and should not be overridden without very good reason.
